Can Indian Paintbrush seeds be bought? A few houses down someone has them on the corner of their lot growing everywhere, but I don't know anything about harvesting seeds even if they let me do so. Any other info on this wildflower, anyone?

Native American Seed has most all wildflowers. In south TX I believe.

Wildseed Farms carries them. I have also seen the seed at Redentas. It's not cheap - about $5 a packet - and they are difficult to start at about 40% germination rate. But they are worth it. Mix the seed with sand b4 broadcasting.
